A set of 20 free BibTeX Generator tools for anyone who writes in LaTeX and is tired of bad .bib files.

Paste a DOI, ISBN, PMID, or arXiv ID - get a clean BibTeX entry. Or paste BibTeX and convert it the other way to APA, MLA, Chicago, IEEE, Vancouver, RIS, CSV, Excel, JSON, or HTML.

Why we built it: every free DOI to BibTeX converter we tried did at least one of these wrong broke titles with acronyms (lowercasing "DNA" to "dna"), failed on & or % in titles, dropped subtitles on books, mangled compressed PubMed page ranges, or quietly shipped your DOIs through a logging server. So we wrote our own.

What's different:

• We brace ALL-CAPS words (DNA, RNA, COVID-19, mRNA) so LaTeX won't lowercase them

• We escape & % $ # _ so your file actually compiles

• Pick BibLaTeX (UTF-8 accents) or legacy BibTeX (\"a style) per export

• Paste up to 50 IDs at once, parallel resolution

• ISBN cascade across OpenLibrary Books API → OpenLibrary Search → Google Books (most tools only check one)

• PubMed via Europe PMC (same Medline data, has CORS, full journal names not stubs)

The full set:

Resolvers → BibTeX

• BibTeX to APA, MLA, Chicago, Harvard, IEEE, AMA, Vancouver

BibTeX → data formats

• BibTeX to RIS, CSV (UTF-8 BOM so Excel doesn't garble accents), Excel (.xlsx), JSON (CSL-JSON — Zotero/Pandoc/Quarto compatible), HTML
